What are the advantages of waterproof rubber-sheathed cables over ordinary rubber-sheathed cables?

Waterproof rubber-sheathed cables, also known as waterproof cables, are cables that can achieve a certain waterproof capacity, while ordinary rubber-sheathed cables cannot be used for a long time in environments with water or humidity. Below, the author will introduce waterproof rubber-sheathed cables and the differences between them and ordinary rubber-sheathed cables.

1. Rubber-sheathed cables

Rubber-sheathed cables are a type of flexible and movable cable that uses multiple strands of fine copper wires as conductors and is wrapped with rubber insulation and rubber sheaths. Generally speaking, it includes varieties such as general-purpose rubber-sheathed flexible cables, welding machine cables, submersible motor cables, radio equipment cables and photography light source cables.

Rubber-sheathed cables are classified into heavy-duty rubber-sheathed cables (YC cables, YCW cables), medium-duty rubber-sheathed cables (YZ cables, YZW cables), light-duty rubber-sheathed flexible cables (YQ cables, YQW cables), waterproof rubber-sheathed cables (JHS cables, JHSP cables), and welding machine cables (YH cables, YHF cables). YHD cables are tin-plated power connection wires for field use.

2. Waterproof rubber-sheathed cables

Waterproof rubber-sheathed cable models: JHS, JHSP

Product Description: The JHS type waterproof rubber-sheathed cable is used for uploading power to submersible motors with an AC voltage of 500V and below. It has excellent electrical insulation performance under long-term immersion in water and relatively high water pressure. The waterproof rubber-sheathed cable has good bending performance and can withstand frequent movement.

JHS waterproof cable 300/500V and below waterproof rubber-sheathed flexible cable for submersible motors is used to connect submersible motors with an AC voltage of 300/500V and below. One end of the cable is in water, and the long-term allowable operating temperature does not exceed 65℃. JHS 6KV waterproof rubber-sheathed flexible cable for submersible motors is suitable for 6KV drainage submersible electric pump power transmission. The long-term allowable operating temperature shall not exceed 65℃.

Specification and model of waterproof rubber-sheathed cable

JHS waterproof cable insulation material: The insulation adopts waterproof rubber. The filling of the cables also uses waterproof rubber. The cable sheath adopts a waterproof rubber sheath, which is suitable for submersible pumps, coal mines, underwater operations, underwater landscape lights and other water treatment equipment. This product uses high-density rubber and has functions such as waterproofing.

Iii. Differences between Waterproof Cables and Ordinary Rubber-sheathed Cables

The JHS type waterproof rubber-sheathed cable is used for power transmission of submersible motors with an AC voltage of 500V or less. It has excellent electrical insulation performance under long-term immersion in water and relatively high water pressure. The waterproof rubber-sheathed cable has good bending performance and can withstand frequent movement.

2. Ordinary cables are usually rubber-sheathed flexible cables, while waterproof cables are generally equipped with aluminum-plastic composite tapes and are suitable for underwater and perennial humid environments. This cable also needs to be protected from pressure and biting (rodents).

3. Rubber-sheathed cables also have water resistance, but they are not professionally waterproof. However, wires and cables all have water resistance in different ways. First of all, not all cables are waterproof. Whether they are waterproof or not is determined by the environment in which they are laid. Generally speaking, waterproof cables include those laid in inland river channels or on the seabed. This type of cable usually has a longitudinal waterproof isolation layer and is generally armored.

4. Waterproof rubber-sheathed cables and submersible pump cables: mainly used for submersible motor matching, with models JHS and JHSB.
